"It lives extremely well in your home and we have seen dengue now in over 100 countries in the world. That's why I think the W-H-O is being precautionary and saying Zika could spread," said Global Head Research of Sanofi Pasteur, Nicolas Jackson. The virus thrives in urban areas.

So far, Brazil is the hardest hit country. According to the Washington Post, one million cases have been reported in the country alone.
